Mining Pool Payout Schemes

The Importance of Payout Schemes

Last week there was a lot of talk about the profitability of the Ocean mining pool. The profitability seen by miners plays hand in hand with the number of blocks mined. In this article we take a deeper dive in the various payout schemes used by pools.

The payout scheme determines how rewards are distributed among pool participants. Choosing the right scheme is crucial because it can directly impact earnings, especially over the long term. It’s essential to understand these mechanisms to optimize your profits based on your resources, mining strategy, and risk tolerance.

Common Crypto Mining Pool Payout Schemes

1. Pay-Per-Share (PPS)

How It Works:

Under the Pay-Per-Share scheme, miners are paid a fixed reward for each valid share they submit to the pool. A “share” represents proof that a miner has done some work contributing to solving the block.

The pool operator assumes the risk of variability. They pay miners upfront for their work, whether or not the pool successfully mines a block. The payment rate is predetermined and based on the cryptocurrency’s network difficulty and block reward.

Pros:

• Consistent Payouts: Payments are steady, as they depend solely on the number of shares submitted rather than the pool’s mining success.
• Lower Risk: Perfect for miners seeking predictable returns without worrying about unlucky block-finding periods.

Cons:

• Higher Pool Fees: Pools often charge higher fees (5-10%) to compensate for their financial risk.
• Lower Long-Term Rewards: Over time, PPS payouts can be less profitable than riskier schemes, especially during lucky periods.

Example:

A miner submits 100 shares in a pool offering $0.10 per share. Regardless of whether the pool mines a block, the miner earns $10.

2. Pay-Per-Last-N-Shares (PPLNS)

How It Works:

Pay-Per-Last-N-Shares distributes payouts based on the last “N” shares submitted by miners. This scheme only rewards miners if the pool successfully mines a block. The “N” in PPLNS represents a rolling window of shares, ensuring consistent payouts based on miners’ contributions during that period.

Unlike PPS, payouts fluctuate because they depend not only on shares but also on whether the pool finds a block.

Pros:

• Higher Long-Term Rewards: Typically offers better returns than PPS during favorable mining conditions.
• Rewards Loyalty: Being active in the pool continuously pays off, as the rolling window rewards persistent effort.

Cons:

• Unpredictable Earnings: Payouts fluctuate based on pool luck and block discovery.
• Higher Risk: Miners may labor for days without payment during unlucky periods.

Example:

A pool solves a block containing 1 BTC. If you contributed 10% of the last 10,000 shares, you’d receive 0.1 BTC minus pool fees.

3. Full Pay-Per-Share (FPPS)

How It Works:

FPPS builds on the PPS model by distributing not just block rewards but also transaction fees collected by the pool. Since block rewards alone may not fully capture profitability, FPPS ensures miners also benefit from traffic on the blockchain.

Pros:

• Higher Earnings than PPS: FPPS payouts consider both block rewards and transaction fees, boosting payouts during high network activity.
• Predictable: Like PPS, rewards are consistent and independent of mining luck.

Cons:

• High Pool Fees: To offset their increased payout obligations, FPPS pools often charge higher fees than PPLNS or PROP.
• Dependency on Blockchain Traffic: Rewards are only higher when transaction fees increase.

Example:

If a miner submits 200 shares in a pool where the FPPS rate is $0.12 per share (considering transaction fees), they’d earn $24 regardless of block outcomes.

4. Proportional (PROP)

How It Works:

The proportional scheme divides block rewards among miners based on their share contributions during a mining round. A mining round covers the period it takes to solve a block.

Payouts are only made once a block is successfully mined, and rewards are divided proportionally to the miner’s contributions.

Pros:

• Straightforward: Easy to understand and calculate.
• No High Fees: Pool fees for PROP schemes are generally lower.

Cons:

• Highly Variable: Miners earn nothing if the pool doesn’t mine a block.
• Favoring High Hash Rate Miners: Those with higher computational power naturally receive larger shares, disadvantaging small-scale miners.

Example:

If you contributed 20% of shares in a round where the pool mined 2 BTC, you’d earn 0.4 BTC minus fees.

Choosing the Best Payout Scheme

Selecting the ideal payout scheme depends on your goals, resources, and risk appetite. Here are some tips to help you decide:

1. For Consistent Income:

• • Choose PPS or FPPS for reliable earnings. These schemes are perfect for miners with limited resources who prefer fixed returns.

2. For Higher Long-Term Gains:

• • Opt for PPLNS if you can tolerate variability. Consistent participation will pay off during lucky streaks.

3. For Simplicity:

• • Go with PROP if you want an uncomplicated payout structure and don’t mind volatility.

4. Consider Pool Fees:

• • High fees can eat into your earnings. Balance the trade-offs between lower variability (PPS/FPPS) and higher fees.

5. Assess Network Conditions:

• • During periods of high blockchain activity, FPPS may yield greater rewards due to transaction fee inclusion.

Final Thoughts

Crypto mining pools offer a fantastic way for miners to collaborate and share rewards. However, payout schemes significantly influence your mining profits. By understanding how PPS, PPLNS, FPPS, and PROP work, you can align your mining efforts with your financial goals and risk tolerance. Whether you prefer consistent payouts or high-risk, high-reward strategies, choosing the right scheme is key to mining success.

Start by evaluating your computational power, mining goals, and ability to weather uncertain periods. Then, join a mining pool with a payout scheme suited to your needs, and watch your crypto earnings grow!
